- Ta all lwhom zr't may concern.'

Be it known 4that I, CHARLES FRANCIS JENKINS, a citizen of the United States, and

a resident of Washington, in the District olf Columbia, have invented Certain new and useful Improvements in Flexible Reinforced Transparent Sheets, of which the following 'is a specification, reference being had thereln to the' accompanying drawing.

This invention relates to Ireinforced, flexi ble, transparent sheets such, for example,

f as are to be used in windows in automobile tops and like situations.. Neither ordinary glass nor Celluloid has proved satisfactory. So far as I am aware, there has heretofore been no such windowpanes which'were in expensive, durable, fully jtransparent, and of desirable size. To provide panes which have all theseadvantages and are, further,

so light that their weight will not deform,

the kleather or fabric in which they are insertedand supported, is the object of this invention. With this object in view, I place non-stretching filaments between very thin closely adjacent sheets of highlytransparent material which is light and flexible.

Inthe accompanying drawings, Figure 1 is a view of the broad facev of with my invent1on. l

a sheet.

Fig. 3 1s an analogous section illustrating mmy method of producing such sheets.'

A represents the body of In these gures having'between two thin a sheet or pane y ytransparent sheets, C, filamentary wires or threads. B which are 'pliablel and practically non-extensible'. The transparent sheets I closely fit the entire freesurface of each filament B and are themselves substantially inf tegralwith'each other fdlbsely alon sidesaid ilamentS,-^in"this. case shown as anetting 1 sheet,-af ter they .have been coated with material adapted to soften and weld celluloid, covering the filaments with a similar 1 specification of Letters ratent.

f, celluloid sheet and adding a second thick sheet G similar tothe Sheet F, and pressing all the superposed sheets between rigid plates H, I. Under slow, heavy pressure, 6 6 the celluloid, softened temporarily along the filaments, is forced into intimate contact with the entire free .surface of the wires, and near these wires the two sheets are fully united with each other, the softening mate-60 rial having been Aforced -outward slightly under pressure. It is preferred to use little softening material because it is not desired to impair the transparency\of the constituent sheets at any ver from the filaments. T e sheet when completed is very light, and highly transpai'ent, except substantiall at the wires, where the softening material injures transparency.

The sheet is, then,4` well adapted forvari- 70 ous uses, and when used 'in curtains and the like it may be rolled. In curtains, these Windows are usually at some distance from -rthat margin at-which rolling begins and hence the windows bend about Yrolls so large 7 5; that'the filaments do notlbecome perma-v nently set. l

One celluloid sheet is sometimes omitted., the filaments being (coated with lastic celluloid, placed upon a celluloi sheet and 80 pressed as when two sheets are used. WhatI claim is: 1. The combination with two superposed` flexible sheets of transparent material, of

non-Stretching. netting interposed between `86 .the sheets and having its mesh forming elements adhering to both sheets, whereby the two sheets are connected only along the interposed reinforcing wires.

' 2. flexiblereinforced transparent sheet 90 'consisting of a sheet ofnon-stretching netting interposed between -very thin trans-l parent sheets of celluloid which are in intimate contact throughout with the constii 'tuent members of the netting and are inte'- ,95

rally united with each other only in regions c osely adjacent to each side of said mem- In testimonylvhereof I hereunto aix my signature.
